iOS 5 is here! Geofencing, new Voices in Voice Command/Siri, and Notification Center for all!

We all know how heartfelt iOS makes you seem (Cards), how much control it gives you for managing your network (Airport Utility), and how it will easily turn you into a stalker (Find Your Friends), but what about all the day-in and day-out things that truely make the upgrade process worth it?

Speak to me (not related to Siri)

One new feature I haven't seen mentioned much is that you can now add a 'Speak' option to every text selection popup, so you can read SMSes or web pages. You can turn it on in the Settings -> General -> Accessibility.

I was going to command and say "surely you mean right to left" as would be expected with any another app, but after opening Calculator.app I realized that the numbers do come out FROM the right. However, I will note that swiping in either direction (left to right OR right to left) will remove a number. Awesome!

View third-party app art at Lock Screen exclusively

When using an app that publishes song information/cover art to the lock screen (e.g. Music.app, Spotify), you can tap anywhere on the Lock Screen except an actual lock screen element (bars, unlock slider, etc.) to hide all of the lock screen's bars and other information in order to have a clean picture of nothing but the cover art, taking the place of your lock screen wallpaper.

While playing music via Spotify, the lock screen normally:

After tapping the background (tapping any of the bar areas will not work):

Unified Single Caller Log

I'm not sure when this happened, but I only just noticed it, but when viewing the recent calls list, of you click the little arrow next to the caller name on the right, you get a detailed list of the relevant calls. This was there before, but only showed completed calls, not is shows cancelled calls where you hung up before receiving an answer or voicemail. Using for proving you tried to call, although it won't show "call failed", it will show cancelled in it's place where a call did actually fail, like for me earlier today...

Bluetooth Volume Control, and Bluetooth Text Display

Simply that the volume control on my stereo bluetooth headphones now actually controls the volume of my iPod Touch - AND the currently playing track is displayed on the Bluetooth module. Looks like they've sorted that one good and proper!
